Hi Florido, if ARC or other middleware providers uses this information, do you think there is the chance that 2.1 could be recognized as an invalid version and thus we will need to update the ARC and cloud middleware providers as well?
ARC will just do things in such a way that the information is always published according to the schema installed in the system. There will be no need for update. I am resposnible for that piece of code. So far we don't have any cloud extension to ARC, that is, there is no current plan to publish cloud objects. It might happen in the future, but this we discuss once we have a working schema. Obviously if the system where ARC runs ships GLUE2 LDAP schema 2.0, cloud objects will just be dropped. I don't know about the cloud middleware providers. It all depends on how they use this info. Cheers, Florido
Cheers, Salvatore.

Hi,

Since only the BDII version is published today, the easiest way is to increase its version number, unfortunately. At the same time we may want to consider publishing the schema version explicitly.
I'd like to remind that since I took over the LDAP schema I introduced a version field in the file for the purposes detailed above:
grep -A12 '00-Version.schema' /etc/ldap/schema/GLUE20.schema # File: schema/00-Version.schema # URL: http://redmine.ogf.org/projects/glue-wg # Doc: GLUE Specification 2.0 (March 3, 2009) # Section: - Version file # Authors: Laurence Field (laurence.field@cern.ch), CERN # David Horat (david.horat@cern.ch), CERN # Florido Paganelli (florido.paganelli@hep.lu.se), Lund University # # # Schema Version: 2.0 # Last updated: 2014-07-02 #
ARC already used this information to do certain things with the LDAP tree.
I read somewhere that there might be smarter ways to do this, for example telling the LDAP server itself and perform a special query on the schema, but these are not implemented and usually badly documented.
Cheers, Florido
